mpnoveMnN-r 1N snm-BRAKES.

` The Schedule referred in these Letters Patent and making part of the same I I, GEORGE W. SANBORN, of Gilmanton, in the county of Belknap, and State of New Hampshire, have invented- I first construct an iron dog, marked o in iig. 1, with the iron arms b b, and then attach to the arm b a hinge -lever marked a a. I then' attachA4 the dog c,- witli the lever or brake, to the `rear end of the sled-runner, by vpassing a rivet or bolt through the ends of the arms b b, and by passing a rivet or bolt through the end of the lever or brake d` d. i

y I tillen att-ach a rope marked k k to the levers d d in the opening marked E E, and pass therope under the second bar of the sled, the rope being held up by a staple driven into s'aid bar on the under side of said second bar, and thenpass said rope thro ugh the first har of the sled, through two holes bored in said first bar. I then fasten to the ends of the ropes k k a rope marked K, and pass it along the sled-tongue under I claim, as my inventionthe ring of the yoke, ima groove which is cut in the sled-tongue to prevent the ring from binding the rope. I then pass the 'rope around a truck or roller, G,Yin iig. 2 which is placed in the end of the sled-tongue, and fasten the ,ropeto the yoke Y by the hook h, as seen in fig. 2.

When'it is necessary to use the brakes, ythe attachment is made as setlforth', and the cattle, by `holding back on the yoke, draw on the levers or brakes d. d by means of the rope K k k, and the. dog is forced int-o the ice or snow. n Y

When the cattle start forward the' ropeis slackened,

and the dogs are throw'n out ofthe snow or ice by the weight of the sled. y

When the brakes are not Wantechor it becomes necessary to back tl1e'sled,the rope K is unfastened from the yoke and tied into the ring of the yoke and the bra-kes are released. y

The same method of hinge-levers may be: applied to brakes for wagons or carts.

Claim.

The combination of the do',r C and arms b b, The hinge-lever or brakes d d, attached by the ropes K- la k to the yoke, substantially as and for thepurpose hereinbefore set forth,
